So looking at the specs for the sc34 on precision's website, the inducer on the exhaust side is the same for both the .48 a/r and the .63 a/r. Now the exducer differs...the .48 a/r has a larger side (2.228") vs. the .63 a/r (which has 2.121") Why? Larger the wheel faster it would get out with less back pressure...Or is it that the 2.121" side would have more force has it exits?

confusing...
